A surface condenser or steam condenser is a water-cooled shell and tube heat exchanger used to condensate the exhaust steam from the steam turbine in thermal power stations. The steam is converted from a gaseous to a liquid state at a pressure level below atmospheric pressure.
A steam condenser is a closed vessel-type heat exchanger applied to convert low-pressure exhaust steam from the turbine to water. A steam condenser is a mechanical device employed to condense the exhaust steam of the turbine into the water.
It conducts this process with the help of cooling water that circulates inside it from the cooling tower.
